Foamable hot melt adhesive compositions and use thereof

A foamed adhesive comprising about 20 to about 80 V/V % of foamed gas or air and 80 to about 20 V/V % of an adhesive composition prepared with

• (a) a hot melt adhesive comprising a polymer selected from the group consisting of ethylene-acrylate, polyolefin, and mixtures thereof, and optionally a wax, a tackifier, a plasticizer, and an additive;
• (b) from about [3] to about 10 wt % of an olefin block copolymer having a melt index of equal to or greater than 5 g/10 min measured in accordance with ASTM D1238 at 190° C. and a DSC melting point greater than 100° C.;
• and
• (c) optionally, from about 0.05 to about 10 wt % of a foam cell promoter;
• wherein the ratio of the polymer in the hot melt adhesive to the olefin block copolymer is in the range of about 20:1 to about 2:1.
